| 摘 要： | 提出一种基于DSP的谷物含水率测量方法.谷物通过自身重力导入到测试腔内,由MCU和DSP为核心器件构成的测试系统对谷物含水率进行测量、存储,并通过LCD显示.经过测量的谷物,通过螺旋输送器排出,进行下一步测量.系统通过DS18S20温度传感器对谷物温度进行测量,并对温度予以补偿.该方法可使谷物含水率测量误差低于1%,优于常规测量方法.

| Abstract: | A grain moisture measuring method based on DSP is studied.First,the grain is leaded-in measuring capacitance by gravity.Secondly,the grain moisture is measured through MCU and DSP,and the measured data are stored or displayed on LCD.Finally,the measured grain is ejected by a discharging screw feeder,and a measuring cycle is finished.A DS18S20 is adopted to detect and compensate the temperature in the process of measuring grain moisture.The measuring precision is higher than 1% RH,and exceeds the conventiona... |
